' CONTROLLING-VALVE.

To all whom it may concern:

Be it known that we, LLEWELLYN E. JONES, JOHN W. BREAKEY, and WILLIAM F. GAsEY, citizens of the United States of America, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Iniprovements in Controlling-Valves, of which the following is a specification.

This invention relates to improvements in fluid controlling valves and has partlcular application to a valve for controlling communication between a source of'supply and a fluid motor.

In carrying out the present invention, it is ourpurpose to improve and simplify the general construction of fluid controlling valves and to provide a valve which may be held normally closed and which may be automatically opened when conditions war- I of the disk of the valve 32 is a coiled exrant.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claims.

In the accompanying drawing; the figme is an enlarged sectional view through a fluid controlling valve constructed in accordance'with the present invention, parts being shown in elevation.

Referring now to the drawing in detail, 31 designates a fluid conveying pipe having one end connected with a suitable source of fluid supply and the opposite end adapted to be connected with an appropriate form of fluid motor. Located in the fluid conveying pipe 31 is a controlling valve 32 comprising a casing 33 having a valve seat 34 formed therein and designed to be engaged by a valve disk 35, such disk having a stem 36 extending outwardly of the lower end of the casing 33 and terminating in a knob 37. Surrounding the valve 32 is a casing 38 constructed of any suitable material 'and secured within the casing 38 is an electro responsive device composed, in this case,

of a solenoid 39 and a core within such solenoid. Depending from the lower end of the core withinlthe solenoid isa stem 40. Secured-to one end wall of theca'sing 38 adjacent to the lower end of the stem 40 is a stationary support or base plate 40 and pivotally connected to the plate 40' is a lever 41 having pivotally connected thereto Specification of Letters Patent; Application filed November 26, 1913. Serial No. 803,307,

Patented May 18, 1915.

' adjacent to the pivoted end thereof a link 42, the other end of the link 42 being in turn pivoted to one end of a link 43 through the medium of a break joint 44, the other end of the link 43 being pivoted to the base plate 40 below the lever 41;- The lowerend of the stem 40 connected with the pllinger or core of the solenoid 39 is pivoted tb' the connected ends of the links 42 and 43 and in the normal positioii of the core, that is to say, when the solenoid 39 is denergized,

the links 42 and 43 are in alinement with each other and the lever 41 maintained in horizontal position, and in this position of the lever 41 the upper edge thereof engages the head 37 on the lower end 'of the stem 36 of the valve disk 35 and maintains such disk 7 in closed position so that communication between the motor and the source of fluid supply is cut off. Surrounding the stem 36 pansion spring 45 havin one end abutting posite end in engagement with the head 3 such spring acting to move the valve disk.

35 to open position succeeding the movesolenoid.

ment of the lever41 under the action of the Upon the energization of the solenoid 39 the core thereof is drawn upwardly whereby the shank or stem 40 on the lower end of such core breaks the joint 44 and so'perm'its the lever 41 to gravitate to lower position whereby the spring 45 reacts to open the valve 32. v

I It, is to be, understood that, inorder to translate the upward vertical movement of the core into the downward swinging movement of the lever41, either the pivotal con-, nection of the parts concerned must embody a lost motion arrangement in the pin and slot joint, or the stem 4Q mustbe pivoted to the core. j

The outer end .of the'lever 41 is equipped with a handle 47 and, in the present instance, a push button switch 48, is disposed in the path ofmovement of the handle .47. This push button switch may control an electric signal circuit and when the-lever gravitates to lowered position the handle will engage the push button switch '48 and so close the signal circuit thereby energizing a signal upon the opening of the valve. e end wall of. the casing 38 adjacent to the handle 47 of the lever 41 is preferably provided with a hand hole whereby access may be had to the interior of the casing to restore the parts to normal position succeeding the energization of the solenoid 39.

We claim; 1. A fluid controlling valve, mechanism for holding said valve normally closed comprising a lever, a link having one end pivoted to said lever, a stationary support, a second link having one end pivoted to said stationary support, and a break oint con nection between the remaining ends of said for holding said valve normally closed commea re prising a lever, a link having one end pivoted to said lever, a stationary support, a second link having one end pivoted to said stationary support, and a break joint connection between the remaining ends of said links, a core connected to said links at the break joint therein, a solenoid controlling said core, means for energizing said solenoid whereby the joint" between said links will be broken, and a spring for actuating said valve to open position succeeding the breaking of said joint.

In testimony whereof We afiix our signatures in presence of two witnesses.
